Reply To: H9 Y-Cable to use both an Aux switch and Expression pedal

[nickrose]

First, you need the latest version of H9 software (4.8) – using both switch and pedal did not work in earlier versions.

Then, check UTILS.EXPTIP is set to PEDAL. This is the default.

Connect the pedal between TIP and SLEEVE. This is probably one of your mono jacks.

Connect the switch between RING and SLEEVE. This is probably the other mono jack.

If the pedal is not covering the full range, set  UTILS.PDLCAL to ON, wiggle the pedal over its full range a few times, then set it to OFF>.
